About the International League of Polygraph Examiners

The International League of Polygraph Examiners (ILPE), headquartered in the United States of America, is a voluntary professional polygraph association composed of highly qualified polygraph examiners in the private, law enforcement and government sectors from around the world, determined to protect the public by verifying the truth.

Working at the international level, the ILPE is dedicated to providing a valid and reliable means of verifying the truth, and advancing and defending lie detection as a scientific discipline and profession serving the public good. The ILPE assures the highest level of professionalism among polygraph examiners by establishing standards of ethical practices, techniques and instrumentation, as well as providing polygraph school accreditation and continuing polygraph education.

The ILPE encourages and facilitates the increase and diffusion of polygraph-related knowledge among polygraph examiners through professional contacts, reports, papers, discussions, meetings and publications. The ILPE develops and maintains cooperation with other international polygraph associations and professional associations in matters of mutual interest and of benefit to the polygraph profession. Furthermore, the ILPE is committed to educating the public about the positive impact and benefits of the polygraph.

Membership in the International League of Polygraph Examiners is a privilege. In order to become an ILPE member, a polygraph examiner must graduate from an ILPE and/or an APA (American Polygraph Association) accredited polygraph school, and utilize ILPE and/or APA approved polygraph instrumentation meeting strict international quality standards. The ILPE governs the conduct of its members by requiring adherence to the ILPE Code of Ethics and a set of ILPE Standards of Practice.
